Patent CH-676903-A5 (CH)
Title: Information transmission system for train - uses coded microwave signals fed between successive train sections
Inventor: JAEGER WALTER DIPL-PHYS
IPC: B61L15/00
Filed: 1988-08-02
Abstract: The transmission system allows information and command signals to be transmitted from one section (1) of the train to the next (3).  It uses a coded microwave transmitter (6) and a corresp. microwave receiver (7), each coupled to a respective transmitter (8,9). Pref. the transmission path for the microwave signals is verified by transmitting the received data back to the first train section (1).

Title: Flexible sunroof for a motor vehicle
IPC: B60J7/06
Filed: 1978-03-28
Abstract: The flexible sunroof for a motor vehicle comprises a fixed rear cap (12), a front cap (13) sliding from the front backwards and vice versa in the opening of the roof (P), a flexible cover attached to these two caps, a casing (14) on which the front cap (13) is mounted and by the interposition of which it is driven, and a mechanism which generates a movement for lowering and pressing the front cap (13) against the front edge of the opening in the roof when the sunroof is closed and vice versa, and an unsticking and raising movement for this cap when the sunroof is opened.

Title: parallel frequency converter network connection method
Inventor: ROHNER RONALD
IPC: H02M7/493
Filed: 1990-11-19
Abstract: The parallel frequency converter network uses active compensation control for controlling the current distribution between the individual converters.

Patent CH-677629-A5 (CH)
Inventor: WILHELMSON JACK L
IPC: B23K3/00
Filed: 1987-10-27
Abstract: A soldering iron (10) is temperature controlled by temperature control circuitry (20) in handle (16). The temperature setting of the iron is changeable only by the replacement of a laser trimmed highly accurate resistor in the control circuitry establishing the set temperature. A removable key (50) plugged into a socket (24) at the junction of the handle (16) and a tube (14) supporting the tip (12) carries the resistor. In order to change the set temperature the handle (16) must be disassembled from the tube (14) to replace the key (50), with another key carrying a resistor establishing a different set temperature. The key (50) is visible through a window (38) in the handle (16) and is marked to indicate the set temperature to be maintained by the control circuitry. Thus, a soldering iron having both accurate temperature control over a range of preselected temperature and protection against on-station worker adjustment of soldering tip temperatures to other than those prescribed is provided.

Patent CH-661264-A5 (CH)
Title: Process and plant for removing urea and ammonium from bathing water
Inventor: GRUETER PETER
IPC: C02F1/76
Filed: 1983-11-09
Abstract: The bathing water to be treated is passed via an inlet line (1) into a first aeration chamber (4) and there aerated with fresh air in fine bubbles. Before the introduction, CO2 is added to the fresh air via a line (17). After the first aeration, the bathing water passes into a first reaction chamber (7) which contains a bed (10) of coarse-grained activated charcoal enriched with urea-degrading bacteria. In the upper region of the bed (10), chlorine and chloramines are degraded, and in the lower region, urea and ammonium are degraded by the bacteria. The partially treated water is again aerated with fresh air and CO2 in a second aeration chamber (6). The residual urea and the residual ammonium are almost completely degraded in a second reaction chamber (8). In this treatment, the sodium nitrite content of the water is also substantially reduced. <IMAGE>

Title: Device for transporting plates of stone in a vertical position
Inventor: TRUFFER PIUS
IPC: B65D19/08
Filed: 1983-11-17
Abstract: Plates of natural gneiss or quartzite are placed against one another either in a vertical position or in a loose manner on a loading platform or are transported lying in tiers on wooden bases. The intention of the invention is to transport natural plates of stone in a vertical position on a wooden base. An iron construction in a U-shape (1) is fitted laterally to the left and right in each case onto a wooden base (usually of the dimension 120 x 80 cm). These two iron constructions are connected at their ends by two cross struts (2) which can be fitted on. This iron structure then allows the wooden base to be loaded with plates of stone in a vertical position. <IMAGE>

Patent CH-564188-A5 (CH)
Title: Monitoring paper mfr - including basis weight measurement
IPC: G01G17/02
Filed: 1970-06-19
Abstract: The basis weight of sheet material i.e. paper, is measured by exposing the material to radiation (beta, alpha or X-ray) in the form of a succession of events having different energy levels, the transmitted or reflected radiation being detected by a detector whose output is coupled to a digital counter. From this count and from counts obtained using a reference sample and air (i.e. absence of material between the radiation source and detector), the basis weight of the material is calculated together with the mass absorption coefficient. Account is taken of the effect of decay of teh radiation source, air density change due to temperature variation, and dirt build-up on the window of the radiation source.

Patent CH-621461-A5 (CH)
Title: Vibrating harrow
Inventor: LELY CORNELIS VAN DER
IPC: A01B21/06
Filed: 1978-10-10
Abstract: The vibrating harrow has a supporting arm (35) which is fastened to a tractor and extends transversely relative to the direction of travel (A) and on which two longitudinal arms (38) extending in the direction of travel (A) are mounted pivotably by means of axles (36). Articulated on the longitudinal arms (38) are implement carriers (40) which extend parallel to the supporting arm (35) and which are likewise connected at their ends, via joints (41), to semicircular arms (42) likewise serving as implement carriers. Working members (44) in the form of rotors having tines projecting downwards are arranged rotatably on the implement carriers (40, 42). During operation, the two longitudinal arms (38) are moved to and fro periodically via an auxiliary shaft (64), a crank mechanism (60, 61) and a rod (59), with the result that the implement carriers (40, 42) likewise move to and fro. This periodic lateral displacement of the implement carriers (40, 42) ensures a uniform tilling of the soil. <IMAGE>
Patent CH-622618-A5 (CH)
Title: Method and measuring instrument for measuring the pH of gases in aqueous solutions, and application of the method
Inventor: WAGNER HANS-RUDOLF
IPC: G01N33/00
Filed: 1976-08-20
Abstract: Withdrawal of the gases which are to be measured, e.g. because of environmental pollution, from the mains is effected by means of a small suction blower which passes the small amount of gas withdrawn through the gas distribution tube (5). The gas leaves the latter through the distribution orifices (6) and the bottom orifice (15). The gas pressure must be higher than the static pressure of the water column in the measuring vessel (3). The outflowing gas is mixed by means of the mixer (8) with the water (7) in the measuring vessel (3). After a relatively short time, the pH of the water is measured. This is used to determine the dosage for neutralising these pollutants in the gas main stream which, e.g., is scrubbed in a scrubber. In a predetermined time, based on the weight of gas drawn off per unit time, the concentration of the acid and/or alkali fractions in the gas is determined. The measuring probe (10) immersed in the water (7) measures the pH electronically with the aid of the measuring amplifier (13). The pH measuring instrument can be used for flowing or non-flowing alkaline or acidic gases which are allowed to be passed directly into the water. Apart from the measuring probe (10) and the measuring amplifier (13), the pH measuring instrument does not require any sensitive, expensive ancillary instruments. It is always available and designed for continuous operation. It requires no maintenance, as the pH measuring instrument is not subject to wear. By means of the pH measuring instrument it is possible for all the commands required in industrial use to be issued by the measuring amplifier. The measuring instrument requires only a water supply and outlet and electric power. <IMAGE>
